What is Wide Color Gamut?
The color range of the human eye far exceeds what typical LCD displays can reproduce. The range of color produced by a LCD display is referred to as its “color gamut.” A wide color gamut display produces an image that more closely resembles the range of color of the human eye.
Wide color gamut is often associated with 4K resolution. However, a display’s color gamut is independent of its resolution. The color gamut is a function of the backlight LEDs and color filters used within the LCD panel.
BT.2020 Emulation
The color gamut of the BT.2020 specification defines the red, green, and blue chromaticity values as being pure wavelengths of light. To achieve this requirement, a laser backlight would be needed. Current display technology is not able to achieve this.
To faithfully reproduce the rendering intent of a BT.2020 camera, a color emulation algorithm is used. Within the available color gamut, the display will accurately reproduce chromaticity values in alignment with BT.2020. Values outside this range will diverge along the limit of the available color gamut as shown in the illustration.
